Evil villain that can’t stand the “teenage chosen one” trope, so they create a powerful spell called “21+”.
It makes a barrier around their evil empire that is impenetrable by minors, even when they have a guardian with them to usher them into your domain.
The young Justice hates this spell, because when you cast “MDNI!!” They end up back at home, far, far away from your evil domain and it’s not fair!! They traveled through so many different lands and places, overcoming obstacles after obstacle to get to your evil kingdom, only for you to tell them to “get off your lawn”!?!?
They are so mad that they keep coming to your evil domain to bug you. Screaming from the barrier to come out and fight them. They call you a coward, a chicken and “not cool”.
You don’t care 🤷
You look down at them, sipping your evil wine while wearing your evil robe with its matching evil kitty paw slippers.
“Don’t y’all have homework to do? Go learn PEMDAS or something.”
Anyways, you’re their favorite villain and they see you as an uncle, aunt, whatever the word for a gender neutral equivalent is.
You have their guardian’s phone numbers on speed dial.
“Superman, if you don’t come and pick up Conner and Jon I will have no other choice but to call Lois and Lex.”
